Four (4) loops will complete the four sides of each quad loop -
6.
Now using the dimensions in TABLE IIb (per side) Mark the end points of each band
element by measuring from the center nail half the length of the side in each direction.
Mark and drive more nails at those points. It is less confusing if you only have the end nails
in place for the band you are fabricating the element for to facilitate this. Also when
completed remove those nails and use then for the next element. This may be facilitated
by simply drilling holes in the board at the appropriate places and using the nails as
"PEGS" for the proper dimensions.
When using this method of winding the elements, it is better NOT to precut the wire.
Use the entire full spool of wire, and carefully wind each element (remember to
include the "connection tails") then cut the wire at that point. (Be sure to add at
least 2" to each side for Directors and Reflectors, and 12" for DRIVEN elements as a
provision for splicing and attaching to the feed point terminals
This board, element-winding jig, can be lain across several saw horses, attached to a
convenient backyard fence or on the side of a building. It is worth the effort to make this
tool as it forms the corners of each element, which can be easily marked and then lined up
on the arms. To minimize tangling and unnecessary wire kinks it is recommended that the
wire loops be lightly taped along their length prior to removing them from the winding jig.
Set these finished elements aside taking precautions to keep them identified and separated
for future use.
Alternatively you could measure the appropriate length of wire per Table II a. and then
carefully measure and mark the wire per Table II b. (total length is 4 X each side length).
Before cutting the wire should be re-measured exactly and marked for the total required
length from Table IIb. (be sure to add 2" to each side for Directors and Reflectors, and
12" for DRIVEN elements as a provision for splicing and attaching to the feed point
terminals). Now with tape or marker pen (if tape mark an arrow indicating which edge of
the tape is used for the marker). Elements should also be clearly identified, i.e., 10 mtr.
driven ele.; 10 mtr. Refl. Ele.; 10 mtr. director, etc., as required. Element wires should be
cut according to dimensions shown in Table IIb, plus the added amounts for splicing and
connections, and the corners marked by using Table IIb "one side" dimensions.
NOTE- If you have taken the time to create the "winding fixture", it is recommended that
you do not cut the wire (per Table Iia), but spool the wire around the "per side nails" from
